SmallChange (SMC) - a 'faster' version of Litecoin which also uses scrypt as a proof of work scheme and is intended for microtransactions.

*) 15 seconds block targets: beat that MinCoin! Wink

   *) 420 699 680 total coins
   *) no subsidy within the first 3 days and after approximately 5 years; in between: 4 coins per generated block
   *) difficulty retargets every 0.35 days
   *) currently peers are looked up over IRC only
   *) currently no block checkpoints are in the code (but could be easily added)

Other than that, this coin is exactly like Litecoin and should by no means be used as a real cryptocurrency. All of the coin parameters are chosen arbitrarily or at most with 'fairness' towards everyone in mind. [..]

But head over here for the client and more information:
https://github.com/bfroemel/smallchange.git

Cheers!

/edit: layout corrections, topic clarifications and notice:
Any mining efforts are probably wasted efforts. Imagine this coin to be like a small Bitcoin testnet with it's own set of (untested) rules.

binary clients:
Please (learn to) make your own builds. Then you only need to trust the source code and your understanding of it: https://bitcointalksearch.org/topic/alternative-block-chains-be-safe-42465

Thanks for the overwhelming interest --> didn't expect that.

updates
2013/04/22 please update before block 15 000

Please include more detailed build instructions for Linux.

It just crunched through 2500 blocks of backlog and while it was doing that 1000 more came in Grin

Awesome. This is ridiculous. I should have been in bed hours ago, but I can't tear myself away.

I'm notcertain the pool supports stratum yet. try just LONGPOLL?

Now I feel like a damn tween but is there a flag in Guiminer-scrypt to turn off stratum? It seems to default to Stratum and get whiny when it's not available. And I'm lazy enough to like guiminers pre-configured GPU settings for using my desktop/dedicate mining.

No worries. Instead of:
stratum+tcp://sc.dontmine.me:29339
just use
http://sc.dontmine.me:29339

edit: Sorry, read right voer teh GUIMiner part. Uhm... I dunno? Shocked

Yeah, I'm on the pool. It pays better when you don't have MH to throw around. Although I've got my CPU mining solo as well, and it's still stumbling across blocks here and there. Not bad for 5KH.

what is your accepted/rejected ratio

About 15% reject rate. I restarted a few minutes ago:

i dont know what happen to my rig,stale ratio is extreme high Sad

I don't know what just happened, but the pool is suddenly significantly more responsive. If this happens to coincide with bopbeep leaving for a few minutes, that seems to imply SMC needs a pretty beastly server to run a pool.

is there any pool ? Roll Eyes

except sc.dontmine.me

don't think so

because i saw this: Grin

Net Hash: 8.98 MH/s
Pool Hash: 2.47 MH/s

I think the Pool is severely under-representing itself right now. If I had to guess, the pool is closer to 6.5MH atm. But that's not terribly important, compared to working on the backlog and keeping things running orderly. We can worry about the front-end later. :-p

have you joint the pool yet ? Grin

or still solo mining

So some learning experience:
The scripts for the mmcfe assume that they get run at least once every 120 confirmations. Not so true right now for smallchange

So It's crunching the backlog right now and it should pay out soon, there's a lot of unclaimed coins on the pool's wallet and I'm trying to get the payments generated.

Edit:

use --queue=0 --expiry=1 -s 1

any ideas why im getting 75% stales or why my kh's no longer show up on the pool?

Yeah kh update is deferred until the share calc script has finished up, and the stale rate is high as a function of block work changing so often, so it will probably be bad until

I don't envy you. You're basically taking the brunt of a huge pile of traffic. Thank you.

I assume you're trimming front-end functionality to allow more CPU time on the backlog? It's stopped updating a few minutes ago.
